Kyocera 1T02X90NL0 Black toner cartridge

What you are buying, and what you give up

This is a compatible, and a premium one. Katun made it to work in the same machine as Kyocera's 1T02X90NL0. It is not a Kyocera product, it does not carry Kyocera's warranty, and on a machine still under the maker's warranty or on a maker's service plan the genuine is sometimes the only cartridge allowed.

The honest part, from a long time in this trade. On a machine that is being looked after, a compatible is a real option. On a machine nobody is maintaining, a poor cartridge can streak, leak or take the drum with it, and a drum costs far more than the cartridge ever saved. Keep the machine clean and serviced and this is a sound way to cut a running cost. Do not, and it is a false economy.
